摘　　要：近年来,基于原子精密谱的微波测量引起了极大关注,由此诞生了原子微波电场计、原子微波磁场计和原子微波功率标准等。原子微波探测技术是一种本质上的新技术,它把微波场强通过基本物理常量与拉比频率直接联系起来,进而实现电磁量的国际单位制溯源。这种新型微波测量技术的最大优势在于不需要校准,且其理论测量准确度远高于传统电子微波测量技术。主要综述了基于不同量子理论的微波场测量技术的基本原理、测量方法和研究现状,并简要地讨论了其未来发展方向。Recently, atomic precision spectroscopy-based microwave （MW） measurement has also inspired great interest because of its potential ability to link the MW quantities with SI units. As a result, relying on various physical principles,many atom-based MW detectors have been developed, such as the MW electrometry, MW magnetometry, and MW power standard. As compared to traditional measurement, the advantage of atom-based measurement is that it does not require calibration, and the field strength is translated into Rabi frequency via well-known atomic constants. An introduction to the basic principle, measurement methods,and state of the art regarding the different atomic MW detectors are introduced. And, an outlook on the new technology is also given in discussion.
